ANSON J. REYNOLDS, or ST. PAUL, MINNESOTA CUSHION TIRE Application filed August 22, 1927. Serial No. 214,514.

It is my object to provide a cushion tire scribed. The openings 9 and 10 are arranged having a novel and efficient. arrangement in pairs, the openings of each pair extending of openings whereby greater resiliency is imin from opposite sides of the tire as shown in parted to the tire While reducing its cost to a Fig. 3. It will further be noted that each minimum. opening is located radially outward from 5 A further object is to provide a tire of this an opening 9, and that the adjacent radially kind which can be readily molded and respaced openings extend in from opposite quires a minimum of rubber or other matesides of the tire as shown in Fig. 2.

Obviously, the piers 7 may be tion of my improved cushion tire; Fig. 2 is tapered somewhat from the outer toward a section taken on the line 22 of Fig. 1 and their inner ends, but it is important to note 15 showing a suitable casing in place on the tire; that no waste material is incorporated there and Fig. 3 is a typical section taken on the in because they extend in the direction of line 3-8 of Fig. 2. the principal compressing forces. I prefer My improved tire, which is formed from to so construct these piers that they are subrubber or other suitable resilient material, 'stantially uniform in width from their outer 20 has the common substantially toric form. to their inner ends. 5

A cushion tire comprising a body of remolds for forming the tire as hereinafter desilient' material having substantially toric form, a series of radially extending piers formed by two series of openings extending in from the sides of said body, each of said piers being continuous in a radial direction from the rim to the tread of the tire and being substantially uniform in width from its inner to its outer end, one of said series of openings being located radially outward from the other series and each opening extending in from one side of the tire substantially to the other side, leaving a continuous tread of substantial width, and leaving transverse connecting members extending between said piers and forming an annular reinforcement between the outer and inner series of openings.

2. A cushion tire comprising a body of resilient material having substantially toric form, a series of radially extending piers formed by two concentric series of openings arranged in pairs and extending in from the sides of said body, one opening of each pair being located directly outward fromthe other in a radial direction, each opening extending more than half way through said body and being narrow and relatively long in a radial direction, and transverse reinforcing lnembers extending between said piers, said reinforcing members and piers being integral portions of the homogeneous tire body and said piers constituting the principal supporting members and the-tire being without a continuous radial, longitudinally extending supporting member;

3. A cushion tire comprising a body of resilient material having substantially toric form and rim and treadperiph'eriesa series of piers, each continuous radially from said rim to said tread peripheries and formed by two concentric series of openings arranged in pairs and extending in fromthesides of said body, each opening extending more than half way through said body, and the outer series of openings being spaced radially inward from the tread, said piers being narrow, relatively long and substantially equal in width to the width of said openings and relatively thin, transverse, reinforcing members extending between said piers approximately midway between the rim and thread peripheries, said reinforcing members, rim and tread peripheries and piers being integral portions of the homogeneous tire body.

4. A cushion tire comprising a body of resilient material having substantially toric form, a series of radially extending piers formed by two concentric series of openings arranged in pairs and extending in from the sides of said body, each opening being of substantially rectangular cross sectional shape, said piers being continuous radially from the rim to the tread of said tire and from side to side thereof and being of substantially uniform width from their inner
